For the scramble.c problem, write a program that: • Has a main () function and another function that has this prototype: void scramble_str(char s[]); • The scramble_str() function scrambles the contents of the string in a random way so that the string has the same length as before, but the contents are all mixed around. It does this in-place, i.e., there is only one buffer that holds a string. You're free to scramble it any way you want to, but use rand () repeatedly so it gets really scrambled. • The main () function will read a string entered by the user into the buffer, call scramble_str(), and output the resulting string. This will be done in a loop forever, until the entered string is the string "bye". When the user says "bye", the program will exit with a polite message. • Do note that reading a string using scanf (), which is the only tool I've introduced you to so far, will just read up to the first whitespace. So, multiple-word strings won't work! Let's use something that will read up to a newline character: gets (). See the supplemental note and an example below. • Make the buffer 50 characters big.

Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.

Question

For the scramble.c problem, write a program that:
• Has a main () function and another function that has this prototype:
void scramble str (char s[]);
• The scramble_str() function scrambles the contents of the string in a random way so that the string has the same
length as before, but the contents are all mixed around. It does this in-place, i.e., there is only one buffer that holds a
string. You're free to scramble it any way you want to, but use rand () repeatedly so it gets really scrambled.
• The main () function will read a string entered by the user into the buffer, call scramble_str(), and output the
resulting string. This will be done in a loop forever, until the entered string is the string "bye". When the user says "bye",
the program will exit with a polite message.
Do note that reading a string using scanf (), which is the only tool I've introduced you to so far, will just read up to the
first whitespace. So, multiple-word strings won't work! Let's use something that will read up to a newline character:
gets (). See the supplemental note and an example below.

Write a function that accepts a number, N, and a vector of numbers, V. The function will return two vectors which will make up any pairs of numbers in the vector that add together to be N. Do this with nested loops so the the inner loop will search the vector for the number N-V(n) == V(m). n and m are indices in the vector of numbers. Example A = [1,2,3,4,5,6, 7] Google(5, A) Return [1,2,3,4] and [4,3,2,1] being the pairs that sum to 5. Notice that each pair appears twice. Try to write code that does not do this.

Write a c++ program that reads in input commands related to a queue with no more than ten elements and performs the specified operations. Note that you should create three files, one for the main, one for Queue.h, and one for Queue.cpp. Those commands are: 'E', which will be followed by a number. You should enqueue that number 'D', which will dequeue the value from the front of the queue and print it, followed by a new line 'K'. which will peek at the value at the front of the queue and print it, followed by a new line 'Q', which will quit the program You can assume that all the input is valid.
Student should be able to develop the programs for stack using arrays and linked list By using C++ software Write a C++ program that reads a data file consisting of each student's GPA followed by the student's name. The program then prints the highest GPA and the names of all the students who received that GPA. The program scans the input file only once. Moreover, we assume that there are a maximum of 100 students in the class. INPUT The program reads an input file consisting of each student's GPA, followed by the Student's name. Sample data is as follows: 3.5 Baharom 3,6 Jason 2.7 Lisa 3.9 Khadijah 3.4 Jamal 3.9 Davendren 3.4 Termizi OUTPUT The program outputs the highest GPA and all the names associated with the highest GPA. For example, for the preceding data, the highest GPA is 3.9 and the students with that GPA are Khadijah and Davendren.
C++ Code dynamicarray.h and dynamicarray.cpp
C++ LANGUAGE In this assignment, you will be writing two objects to heuristically compare the performance of the bubble sort, selection sort, and insertion sort algorithms. To do this, a “Timer” object will be created and compositionally related to a storage class that will load the file contents, execute the sorts in an unbiased manner, handle any memory allocations that need to be made in order to do this, and reports back the execution times of each algorithm on the provided input files for that machine. First you will need to make a Timer object. This object should function like a traditional stopwatch with methods for starting, stopping, resetting, and reporting back times. The design of the object itself is up to you (it should minimally contain methods for the aforementioned ideas), but it must consist of a solitary object that provides interfaces appropriate for being compositionally included as part of a sorting object to facilitate the timekeeping portion of this exercise.…
Write a program in c++ and make sure it works, that reads a list of students (first names only) from a file. It is possible for the names to be in unsorted order in the file but they have to be placed in sorted order within the linked list.The program should use a doubly linked list.Each node in the doubly linked list should have the student’s name, a pointer to the next student, and a pointer to the previous student. Here is a sample visual. The head points to the beginning of the list. The tail points to the end of the list. When inserting consider all the following conditions:if(!head){ //no other nodes}else if (strcmp(data, head->name)<0){ //smaller than head}else if (strcmp(data, tail->name)>0){ //larger than tail}else{ //somewhere in the middle} When deleting a student consider all the following conditions:student may be at the head, the tail or in the middleBelow, you will find a sample of what the file looks like.
